I just installed leopard 2 days ago and now my MBP that i got in july will not go to sleep when i shut the lid or go to the apple then sleep. In Tiger it worked beautifully, but now the light that used to pulse just stays dim white and the display will just cut off, my MBP also gets very hot, like last time i opened it, it was at 175 degrees and i was pretty alarmed, can anyone please help me fix this issue, i would greatly appreciate it if someone could help me out, i really want to be able to put my mac to sleep!
